CROSS-REFERENCE TO RELATED APPLICATION

The application is a continuation of U.S. patent application Ser. No. 16/951,326, filed Nov. 18, 2020, which claims priority to and the benefit of the filing date of U.S. Provisional Patent Application No. 62/937,608, filed Nov. 19, 2019, the entirety of each of which is hereby incorporated by reference herein.

FIELD

The disclosure relates to seating in a bathtub and, in particular, to pivotal platforms for enabling a user to access the seating in the bathtub.

BACKGROUND

Many individuals use a bench in the shower, whether for safety or out of necessity. In a typical combination bathtub/shower, an individual must climb (often, from a wheelchair) over the rim of the bathtub to access the bench. Conventional platforms are sometimes used to assist the individual in traversing the rim of the bathtub in order to enable the individual to access the bench. One such example conventional platform is disclosed in U.S. Pat. No. 9,107,787 to Wechter. The platform is pivotably attached to the bench and comprises a pair of legs that fold down to rest against the ground/floor outside the bathtub. However, when the platform is in a lowered position, the shower curtain cannot be in a closed position. When the platform is in a raised position to allow the shower curtain to close, the platform acts as a vertical barrier that limits movement of the individual's arm.

SUMMARY

Described herein, in various aspects, is a bench assembly for use in a bathtub for showering. The bench assembly can comprise a frame that is configured to sit within a bathtub. A bench can be coupled to the frame. A pivotable platform assembly can comprise a platform support structure pivotably coupled to the frame and a platform coupled to the platform support structure. The pivotable platform assembly can be configured to bias against an upper rim of the bathtub.

A method of using the bench assembly can comprise using the platform to access the bench within the bathtub when the platform is in a lowered position and the pivotable platform assembly is biasing against an upper rim of the bathtub. The platform can be raised to allow a shower curtain to be positioned between the platform support structure and an upper rim of the bathtub. The shower curtain can be closed so that the shower curtain is positioned between the platform support structure and the upper rim of the bathtub. The platform can be lowered to the lowered position so that the platform support structure is resting on, and supported by the upper rim of the bathtub, with the shower curtain disposed between the pivotable platform assembly and the upper rim of the bathtub.

Disclosed herein, in various aspects and with reference to FIGS. 1-6 , is a bench assembly 100 that is configured for use in a bathtub 200 having an interior 202, an upper rim 204, an inner wall 206, and an outer wall 208. The bench assembly 100 can be used to enable an individual (user) to safely and without difficulty traverse the upper rim of the shower as well as comfortably shower when seated on the bench assembly. The bench assembly 100 can comprise a frame 102 that can comprise a plurality of (e.g., four) legs 104. The legs 104 can be adjustable in length in order to configure the bench assembly 100 for various bathtub heights. In some aspects, the legs 104 can comprise telescoping components. In some exemplary embodiments, the legs 104 can each have an inner portion and an outer portion that are slidable relative to each other and lockable in different axial positions relative to each other via, for example, a fastener or detent. In these aspects, optionally, the inner portion can have one or more detents that engage through-holes along the length of the outer portion to lock the inner portion with respect to the outer portion to provide a leg having a desired length. Non-slip feet 106 can attach to bottoms of the legs 104. Optionally, the non-slip feet 106 can be removably attached to the legs 104. Alternatively, the feet 106 can be permanently secured to the legs. It is contemplated that the feet 106 can comprise any conventional non-slip or slip resistant material (e.g., polymer).

A bench 110 can attach to the frame 102 so that the frame supports the bench. The bench 110 can define a horizontal or generally horizontal upper surface. The bench 110 can optionally define contours that are shaped to ergonomically receive portions of a user's body (e.g., portions of the user's legs and buttocks). Optionally, the bench 110 can be padded or unpadded. The bench 110 can optionally define one or more through-holes that enable water to drain therethrough. A backrest 112 can couple to (optionally, be fixedly attached to) the frame 102 and/or the bench 110. Optionally, the backrest 112 can be coupled to the frame 102 and/or the bench 110 via one or more support members 114. The backrest 112 can optionally be perpendicular or generally perpendicular to the upper surface of the bench. The backrest 112 can engage a portion of the back to aid in trunk support. The backrest 112 can optionally be adjustable to various heights. For example, the one or more support members 114 can define vertically spaced holes that are configured to receive fasteners to couple the backrest 112 to the support members 114 in different vertical positions. In further aspects, a quick-disconnect clamp can enable decoupling and adjustment between the backrest 112 and the support members 114. In some optional aspects, the backrest 112 can comprise polymer or washable canvas. In these aspects, it is contemplated that the backrest can be removable for washing.

It can be understood that showers can be configured with the shower head on either longitudinal end of the bathtub. In other words, when facing the wall opposite the rim 204 that the individual must climb over to enter the bathtub, the shower head can be positioned on either the left or the right side. The bench assembly 100 can be selectively configured to face in either direction. For example, according to some optional aspects, the backrest 112 can be reversibly attached (e.g., via bolts and nuts) to extend upwardly from either end of the bench 110 (i.e., on the opposite ends with respect to the longitudinal dimension of the bathtub). In some optional embodiments, the backrest 112 and frame 102 can be coupled in rotationally symmetric fashion so that the backrest 112 can be swapped to the opposite end, thereby allowing the bench 110 to be configured for use with the user facing in either direction (i.e. toward either longitudinal end of the bathtub).

The bench assembly 100 can further comprise a handrail 190. The handrail 190 can couple to, for example, the frame, the bench, or both. Optionally, the handrail 190 can couple to the frame 102 or bench 110 below the upper surface of the bench. The handrail 190 can extend above the upper surface of the bench 110 and can optionally be positioned for use as an armrest and/or for the user to grip for support when moving into and out of the bathtub 200. The handrail 190 can optionally comprise a length of bent tubing. The handrail 190 can be configured to support the weight of the user, thereby enabling the user to grip the handrail when climbing onto and off of the bench 100. The handrail 190 can be positioned on the side of the bench opposite the platform 130 (i.e., on the side adjacent the wall that runs the longitudinal length of the bathtub). Accordingly, it is contemplated that the handrail 190 can be selectively removed and reattached on each side of the bench 110 (e.g., the left or right side relative to the user sitting on the bench and facing longitudinally in the bathtub). Optionally, the handrail 190 can be detachable (e.g., via removing bolts or via a quick-release).

A pivotable platform assembly 132 can be coupled to the frame 102. The pivotable platform assembly 132 can comprise a platform 130 that is pivotably coupled to the frame 102. The platform 130 can be configured to be selectively positioned across the rim 204 of the bathtub 200. For example, optionally, one or more arms 120 (e.g., a pair of arms) can pivotably couple to the frame 102 about an axis 122 by one or more hinges 124. As shown in FIG. 1 , it is contemplated that the arms 120 can be configured for pivotal motion relative to the axis 122, which can extend parallel or generally parallel to a longitudinal axis of the bathtub 200. The platform 130 can couple to the arms 120. In this way, the platform 130 can be pivotably coupled to the frame 102 about the axis 122, and the pair of arms 120 can define a platform support structure. In various optional embodiments, the platform 130 and one or more arms 120 can comprise separate components that are coupled together or can be integrally formed as a unitary, monolithic component. Optionally, the pivotable platform assembly 132 can include only one single arm 120.

In some optional aspects, each of the arms 120 can pivotably couple to respective legs 104 positioned on the side of the frame 102 proximate to the outside of the bathtub. For example, in some optional aspects, a respective pin can be received through corresponding through-holes in each arm 120 and a respective legs 104, with the pin being aligned with axis 122 so that the pins define at least a portion of the hinges 124 and form respective pivotal couplings between the arms 120 and the frame 102. In further optional aspects, the arms 120 can be pivotably coupled to the bench 110 or other portions of the frame 102.

Optionally, an engagement member 140 can couple to at least one of the platform 130 or the arms 120 for engagement with (e.g., biasing against) the upper rim 204 of the bathtub 200. In some optional embodiments, the engagement member 140 can comprise, or be embodied as, a compressible pad that is configured to elastically deform upon engagement with the upper rim of the bathtub. The pad can optionally comprise a water resistant, compressible, resilient material, such as, for example, foam, rubber, latex, polymer padding, or combinations thereof. The compressible pad can desirably reduce the amount of noise caused by engagement between the pivotable platform assembly 132 and the bathtub as well as distribute pressure across the upper rim to inhibit scratching or breaking of the bathtub. Optionally, the engagement member 140 can comprise opposing, downwardly facing projections 142 that define a receiving space 144 (in between the projections) for receiving at least a portion of the rim of the bathtub. It is contemplated that the depth of the receiving space (corresponding to the distance that the downwardly facing projections extend downwardly) can be minimized in order to limit the amount of shower curtain held outside the bathtub. For example, optionally, the downwardly facing projections can extend downwardly less than two inches or less than one inch in order to minimize the length of shower curtain outside of the tub, thereby allowing a lower edge of the shower curtain to be within the bathtub when the engagement member 140 is resting on the shower curtain. In further aspects, the engagement member 140 can be flat or convex. The engagement member 140 is optionally adjustably positionable along the longitudinal dimension of the arms 120 in order to accommodate bathtubs having varying widths. For example, according to optional aspects, the arms 120 can comprise a plurality of holes along their respective lengths, wherein the holes are configured to receive bolts (or other fasteners) therethrough, and the engagement member can be bolted (or otherwise fastened) to the arms 120 at select holes of said plurality of holes along the lengths of the arms. In various optional aspects, it is contemplated that the engagement member 140 can be adjustably coupled to the platform 130 (or the arms 120) so that the spacing between the underside of the engagement member 140 and the upper surface of the platform 130 can be adjusted. For example, an adjustable-length coupling 146 can couple the engagement member 140 to the platform 130. For example, in some optional aspects, the adjustable length-coupling 146 can comprise a spring detent that can be selectively positioned within a hole of a plurality of holes spaced longitudinally along a support member in order to select the length of the adjustable length-coupling 146. In this way, the pivotable platform assembly 132 can be adapted for bathtubs having different depths.

The platform 130 can be pivoted between a lowered position 180 (FIG. 3 ) and a raised position 182 (FIG. 1 ). In the raised position 182, the platform 130 can be above and pivoted away from the upper rim 204 of the bathtub 200 so that a shower curtain can be drawn between the bathtub and the bench assembly 100. When in the lowered position 180, the pivotable platform assembly 132 can bias against the upper rim of the bathtub. For example, for embodiments comprising an engagement member 140, the engagement member can bias against the upper rim of the bathtub. In further aspects, the arms 120 or the platform 130 can bias directly against the upper rim of the bathtub. Optionally, the platform 130 can be horizontal or substantially horizontal when in the lowered position 180. The platform 130 can be spaced from the bench 110 in order to provide sufficient clearance for the platform to pivot with respect to the bench. Optionally, this spacing can be minimized and selected based on the dimensions of the bench and platform.

In some optional aspects, when in the lowered position 180, portions of the arms 120 can be configured to bias against an underside of the bench 110 or frame 102 in order inhibit further pivoting of the pivotable platform assembly 132. For example, when the platform 130 is in the lowered position 180 (FIG. 3 ), the ends 126 of the arms 120 that are opposite the platform 130 can bias against the underside of the bench 110 and/or the frame 102. Simultaneously, the engagement member 140 can bias against the upper rim 204 of the bathtub 200. Thus, in the lowered position, the downward force provided by engagement member 140 can oppose (and, optionally, balance) the upward force provided by the ends 126 of the arms to result in a stable structure. Optionally, the ends 126 of the arms 120 can define an upward projection or define an L- or J-shape that is configured to engage the underside of the bench 110 and/or the frame 102. When the platform 130 is in the raised position 182 (FIG. 1 ), ends 126 of the arms 120 opposite the platform 130 can be spaced from the bench 110 and the frame 102 and can, optionally, be positioned underneath the bench 110.

In various optional aspects, some or all of the materials used in the bench assembly 100 can be water resistant and/or have a water resistant coating. For example, the materials of the bench assembly 100 (e.g., the frame, bench, platform, backrest, arms, etc.) can comprise non-corrosive, water-resistant materials, such as steel, stainless steel, aluminum, polymer, etc.

From outside the bathtub (e.g., in a wheelchair), a user can lower the platform 130 to the lowered position 180. When in the lowered position, the platform can extend across some or all of the upper rim 204 of the bathtub 200. In some optional embodiments, no part of the bench assembly 100 (e.g., no part of the pivotable platform assembly 132) can extend beyond the outer wall 208 of the bathtub 200 when the platform 130 is in the lowered position 180. In further optional embodiments, when the bench assembly 100 is disposed in the bathtub and the platform 130 is in the lowered position 180, no part of the bench assembly 100 (e.g., no part of the pivotable platform assembly 132) can extend beyond the outer wall 208 of the bathtub 200 by more than about two inches, more than about four inches, or more than about six inches, or more than about eight inches. In this way, the shower curtain can be positioned to extend around the distal-most portion of the platform assembly 132 and still have its lower edge positioned within the interior 202 of the bathtub 200. Optionally, in these embodiments the engagement member 140 (e.g., pad) can extend beyond the outer wall 208 of the bathtub 200 by about 2 inches to about 4 inches, and the platform can extend beyond the outer wall of the bathtub by about 0 inches to about 8 inches. The user can use the platform 130 (e.g., sliding across it and onto the bench 110) to traverse the upper rim of the bathtub. Once seated on the bench 110, the user can raise the platform to the raised position 182 in order to permit closing of the shower curtain. The user can then lower the platform 130 back to the lowered position 180 so that a portion of the closed shower curtain is between the upper rim of the bathtub and the engagement member 140. In this way, the platform can be lowered and out of the way of the individual on the bench, while allowing the shower curtain to remain closed during use of the shower.
